The five-year rule and why it exists
Buying costs 6–10% of home price in closing, agent fees and moving. Under 5 years, appreciation rarely covers it — renting wins.
The hidden cost of renting is opportunity: you skip both mortgage forced-savings and home appreciation. The hidden cost of owning is inflexibility.
This calculator invests the down payment at your chosen return when you rent. That is the honest comparison — most rent-vs-buy tools skip it and unfairly favour buying.
